SPRING-VEHICLE.

SPECIFICATION forming part of Letters Patent No. 342,213, dated May 18,1886.

Application filed July 25, 1885. Serial No. 172,010. (No model.)

To all whom it may concern;

Be it known that we, J AooB A. MACK and OHRIsTIAN HANsEN, citizens ofthe United States, residing at Madison, in the county of Dane and Stateof Tisconsin, have invented certain new and useful Improvements inSpring-Vehicles, of which the following is a specification, to wit:

This invention relates to an improvement in vehicles; and it consists incertain peculiarities of the construction of the same, substantially aswill be hereinafter more fully set forth and claimed.

In order to enable others skilled in the art to which our inventionpertains to make and use the same, we will now proceed to describe itsconstruction and operation, referring to the accompanying drawings, inwhich Figure 1 is a side elevation of our vehicle; Fig. 2, a bottom planview of the same. Figs. 3 and 4 are front and rear end views, and Fig. 5is a detail view of the connection of the spring and body.

A represents the front and rear axles, and A the wheels,of aspring-vehicle, of the usual or any desired kind.

B is the body, of any shape or size, provided at each corner with anangle-iron brace, b, from which an .arm or support, B, projects outwarda suitable distance on each side of the body, the end of this arm beingbent at right angles to its main portion, and-formed with a shoulder, b,and a spindle, W, on the end of which is a nut, b, as seen fully inFigs. 3, 4, and 5.

Upon each axle is supported a spring, C, formed of two or moreleaves,which are bent upward and outward from their center, and have their endsbent downward slightly and formed with an eye, 0, as fully shown in thedrawings.

The spindles b of the supporting-arms are inserted in the eyes in theends of the springs and firmly secured by the nuts, which may betightened at any time to take up wear. This forms a direct and rigidconnection with the body, nothaving any links or shackles to rattle; andit will be seen that the ends of the springs under the influence ofweight always rise and fall in a vertical line,and do not lengthen outas they are compressed.

vents any end movement of the body, and holds g it rigidly against anyother motion, besides materially lightening the construction.

It will be observed that the arms B are made of any desired length, anda spring of much greater length than the width of the bodyis readilyused without the use of side bars, and the points of support are spreadenough to bettersupport and distribute the weight and cause the body toride more nearly level under all conditions. The body is, as usual,supported between the end springs, but may be higher or lower thanherein shown, according to the fancy of the builder, it being onlynecessary to bend the supporting-arms up or down to support the body atany desired point. The branching of these irons at their point ofattachment to the body effectually braces the corners, and prevents anystraining of the body when loaded.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

1. In a spring-vehicle, a half-elliptic leafspring having its main orupper leaf elongated, with downwardlycurved ends formed with an eye, incombination with and securely fastened at its center to the head'blockand the vehicle-body, provided with outwardly-projecting arms B, bent atright angles to receive the eyes of the spring, substantially as and forthe purpose set forth.

2. In a spring-vehicle, the halfelliptic leafspring having its main orupperleafelongated, with downwardly-curved ends formed with an eye, incombination wit-h and securely fastened at its center to the rearaxle-tree and the vehiclebod y, provided with outwardly-projecting armsB, bent at right angles to receive the eyes of the spring, substantiallyas and for the purpose set forth.

Intestimony whereof we affix our signatures in presence of twowitnesses.
